Symptom
SSL error with the usual “no no no, connection is not secure” which caused MyAEGEE to be unreachable, and the login from the “OMS JC module” also to fail
Cause
Probably a mix between a deprecation of OpenSSL 1.1 and the fact that we use Traefik 1.7.x which is EoL caused a certificate not generated when it was supposed to (Traefik does automatic certificate generation through Let’s Encrypt)
Mitigation
ssh to the server
install the certbot manually
Stop traefik to free port 80
Generate certificate and copy them to traefik folder (and chown to grasshopper:developers)
Edit traefik.toml
remove acme part
add manual certificates
edit docker-compose and mount the certificates in the container
???
PROFIT!!
Notes
This should not happen again as we will migrate to MyAEGEE v2 soon, which will get rid of Ubuntu 16 (I was even afraid I could not install certbot there..!) and Traefik 1.7.x
